1. Coat a large nonstick or cast iron pan with olive oil. Add onion and saute until soft and translucent. Add butter and garlic paste and saute until garlic paste is fully melted and evenly distributed. Add cauliflower and saute until it begins to soften and brown slightly. Season to taste with salt and Tony Chachere's seasoning.

2. Preheat oven to 350 degrees.

3. Spray a small casserole dish with nonstick spray. Add half of the cauliflower to the bottom of the dish. Layer 1/2 cup mozzarella and 1/2 cup cheddar over the cauliflower. Add remainder of cauliflower and all remaining cheese (mozzarella, cheddar and Parmesan). Bake for 30 minutes.

4. While cauliflower mixture is baking, wipe out same pan you used to saute the cauliflower and coat with olive oil again. Saute onion, bell pepper, garlic and leeks until they begin to soften and become fragrant.
